T a citizen oi: the United States, residing Richmond, in the county of i agile and.

5 fate of Indiana, have invented a and Useful Journal-Be:i1ing, of which the fol- ,mving a specification.

The present invention uppel'teine to :lQHEF ml bearings, and.

withdrawn from the respective and 23', which will permit the bearing to be withdrawn outwardly from the journal box. Attention is directed to the fact, that when the bearing is moved downwardly within the box, the sides of the bearing being inclined, will be spaced from the side walls of the journal box, whereby the bearing can be withdrawn easily. This also permits the bearing to be readily inserted when moved into place upon the bottom of the journal box, and then when the journal box is moved down wardlv or the bearing moved upwardly, the flanges 20 and will be moved into their grooves oi the journal box, andat the same time, the bearing; will wedge into engage ment with the journal box, to provide a tight lit, and to avoid vibrations or rattling. The flange 2 also bears against the shoulder 23 to assist in holding the bearing in place.

The bearing 16 has a longitudinal bore 24-. within which the journal projects concentrio \vith and spaced from the walls of said bore, and a set of longitudinal anti-frie tional rollers are disposed snugly be can be grooves 21 tween the journal and. its bearing, whereby to reduce friction, and to take up the radial strains. The rollers 25 are provided with reduced ends or trunnions 26 received by apertures 28 of retaining rings 2? which are disposed at the opposite ends of the rollers to hold them in proper spaced relation. The remote ends 01 the a .)ertures 28 are reduced, to 1 wide retaining lips 29 for holding antirictional thrust balls 30 The trunnions or ends 26 of the rollers are concaved, as at 31, to fit Hie balls 39, for transmitting; the end thrusts *om the rollers to said balls and vice versa. ihe inner set balls project imvardly from the inner ring 27 and bear against the shoulder 3 to receive the outward thrust of the axle 1, and transfer it to the rollers with the least friction, since the balls 30 can rotate with respect to the axle and rollers. The outer set of rollers project outwardly from the outer ring 27 and bear against an annular abutment or ball race 32 with which the journal box lid 9 is provided, whereby the outward end thrust of the axle is transmitted from the rollers 25 to the journal box lid 9 and journal box 5 by way of the outer set of rollers- 30. By the provision of the anti-frictional rollers and balls, friction is reduced to a. minimum, and the radial and longitudinal strains are therefore taken up with the least amount of resistance. lhe balls 30 are free to rotate in various directions, as they are engaged by the rollers during their rotation about their axes as well as the axis of the journal, and said bells therefore reduce the friction.

The contacting parts of the journal, rollers, balls, journal bearing and lid can be lubricated in any suitable manner ,to reduce wear and friction. The journal box can be provided with any suitable means 33 for attaching it to the frame.
